Two different tickHeights on a rating scale in Psychopy

I know that you can customize the tickHeight on rating scales in Psychopy. I want to have two different tickHeights. here's a rough sketch:

Here's a rough sketch:

is this possible? and if so, how do I do it?

This is the code for the rating scale that I have so far:

myRatingScale = visual.RatingScale(myWin, precision=10, showValue=True, low = 1, high = 10, scale ="", tickHeight=5)

Solution

It is possible but not easy. If you have a rating scale rs like this:

rs = visual.RatingScale( ... lots of parameters here ...)

you can create a new line with whatever tick marks as a set of vertices, and then do

newVertices = [ [x1,y1], .... [xn,yn] ]  # many x,y points -- all up to you
rs.line.setVertices(newVertices)

And only then draw the rating scale. I have not tested this but think it will work (or something similar will).
